"Major retailers are violating California law by failing to warn consumers about diaper-changing pads, nap mats and other baby products made with unsafe levels of a flame retardant linked to cancer, according to legal notices expected to be filed Thursday."

"The notices urge retailers including Amazon, Target and Wal-Mart to recall infant and toddler products made with chlorinated tris or TDCPP. Researchers have found the flame retardant in upholstered furniture and children's products sold throughout the nation.

In October, California started requiring warning labels on products that could expose people to harmful amounts of chlorinated tris. The Center for Environmental Health, a nonprofit group that uses legal action to force toxic chemicals out of household products, tested 19 children's products bought in stores and online after the state's deadline.

Sixteen of the items, which also included crib mattresses and nursery furniture, were found to contain chlorinated tris, the group said. None had a warning label."
